Shoulder pain when lifting your arm across your body

Cross-body movement brings the upper arm toward the opposite side and can load the joint at the front or top of the shoulder. Rotator cuff tendinitis, shoulder impingement, or shoulder osteoarthritis may cause pain with this action. A rotator cuff tear can cause pain with weakness, especially after an injury. Frozen shoulder tends to add stiffness in several directions. Neck-related nerve irritation may cause pain, tingling, or altered sensation travelling into the arm.

Notice whether the discomfort is at the top of the shoulder, deep in the joint, or extending below the elbow. Record what started it, which movements trigger it, and whether sleep or dressing has become difficult.

Reduce movements that sharply reproduce the pain for a short period, while keeping the elbow, wrist, and shoulder gently mobile within a comfortable range. Avoid repeatedly testing the painful motion or carrying loads away from your body. A cold pack wrapped in cloth may soothe a recent flare; follow medicine-label directions and check with a pharmacist if you have health conditions or take other medicines. Arrange a clinical assessment if symptoms persist, recur, or limit work, exercise, or sleep.

Seek urgent medical help after a fall or forceful event if the shoulder looks deformed, the arm cannot be used, or there is sudden marked weakness. Get urgent help for shoulder symptoms with chest pressure, breathlessness, faintness, or sweating. Prompt assessment is also needed for a hot, red, swollen shoulder with fever, or new numbness and weakness spreading through the arm.

Could the location and movement pattern fit a tendon, joint, or neck problem? Do I need a strength and range-of-motion examination? Which activities should I modify, and what exercises are suitable while it settles? What changes should prompt earlier review?
